DEMOUNTABLE-RIM FASTENER.

Specification of Letters Patent 'atenivtllnly1,1915) Application filed March 27, 1918 Serial No. 224.990.

To all whom it If/,Hj/ win-1 ru.

Be it known that l. l lnnoxn .l. llnuun m a citizen of the l nited States, residin; at Vineennes, in the county of Knox and State of Indiana. have invented ('ertain new and useful Lnprovements in Demountahle-llim Fasteners. of Wlllt'll the following is a spot-i fieation.

This invention relates to new and u eful improvements in demountahhrims nnd the primary oh ieet ot the invention is to rovide a vehicle wheel provided with a demountahie tire t';\ t' \'it1lf rim that is serured to the tixed rim of the wheel hr novel type ot t ns-telling means, that is detau'hahlv ronneeted with the Wheel, and when rem ved it is adapted to carry the demountahle rim therewith so as to facilitate the removal of a tire from the wheel.

Another ohjert ot the invention is to pro-- videa devire of this ehnra ter which is easily and simply ronstriu-ted, inexpensive to manu'fzurtiire. and one whir'h will he very ellieient in operation.

\Vith these and munerous other ohjeets in view, my invention ronsists oi the novel fez!" tures of eonstriu-tirm. romhinatiom and urrangement of parts which will he herein re- 'l'erred to and more partieularly pointed out, in the speeitiration and (-laims.

In the aeeompanving drawings:

Figure l is :l t'ragmental section of the device, and

Fig. 52 is a. transverse section through the wheel rim.

In desrrihing my invention. l shall refer to the drawings in Wlllt'll similar retort-nee eharacters' designate corresponding parts.

throughout: the several views.

The numeral 1 designates the fixed rim of a vehicle wheel said wheel being of the eon ventional construction. and the fixed rim thereof having a smooth outer periphery a clearly illustrated in the aeronuianying drawlngs. The demountahle tire carrying rim 2 is of the ronventional eonstruetion. and is adapted to be positioned on the smooth oute'r peripluxry of the fixed rim 1, as is ronnnon to this general. type of device. My invention resides in new and novel means for detachably connecting the deinonntahle rim to the fixed rim and facilitating the re rnoval or replacing of the same thereon.

The means employed comprises a transverse rieeurnnL strip 3 that extends across between the outer face of the fixed run and the t'zu-e ot the demounttahle rim. said strip llt'lllfi' adapted to he interposed tl'urehrtween when the parts are in position as is rlearly shown in Fig. 2 of the drawings. The inner face of the strip 25 is smooth, and is slidahle on the periphery ot' the fixed rim i while the outer tare thereof has its opposite ends rurved ontwardlv as shown at 4, to form a seat adapted to rrrrire the demountahle rim 3 thereon. The outer end oi the strip l is provided with means for detaelmhly eon nor-ting the same to the lilittl rim 1 as will he lu-reinai'ter more full desrrihr-tti 'lhis t-onnreting means t-oiuprises on intogrnl inwardly ex ending lug Ii that extends downwardly adjm-ent the out r ide of the fixed rim 1 and whit-h is provided with an aperture 4' therethrough adiarent its inner end. The aperture ti alines with a transverse opening through the lixed rim 1. adapted to rereire a holt T that has its outer end s-xteu null threaded and props-ting through the aperture 6.

The bolt 7 that is positioned through the lived rim 1 is rigid! serurtul therein and the end that projects from the side of said rim extends outwardly tor a eonsiderahle distanee, as is: elearly shown in the arrompanv inn drawings for :1 purpose to he hereinafter more fully dest-rihed. (he inner fare of the lug I: is provided with a puein; memher that will spare said lug: a short di-- tam-e from the adjacent side ot the tixed rim.

(fonneeted with the outer fare of the lug: 5 is a nut ii that is adapted to he mounted on the projecting; end of the bolt T said nut. t4 luring provided with a hase flange l2 pro itt'tlll; theret'ronn and mounted in a reress it) in the outer fare of said lug. The pro jetting Range 12 ot' the nut hf is held in said reress Irv a locking ring' 11 as (-Iearlvillus trated in Fig. 2 of the drawings. This will swivelly ronnert the nut R with the h1g5 for a purpose to he lu-reinatt'er more fully described.

ln operation. when the various parts ol' the d vice are assembled as is rleurly shown in Fig. '3 of the drawings, it is oluions that the demountahle rim 2 will he serurelv held to the fixed rim of the strip 3, \vhirh has a seat on its outer t'aee tha serurelv holds th (leniountahle rim therein As the strip 35 is secured to the fixed rim 1 there is no possibility of the tire becoming disengaged from the wheel. it only one of the fastening strips is employed, the same is isposed diainner metrically opposite from the air valve, but any number may be used as is found suitable they being spared rircumfereniially around the wheel. When it is desired to remove the demountuhle riin und tire carried thereby from the fixed rim, the nut 8 is rotated, in the proper direction. and as the bolt 7 on Whose projecting end the nut Un'fllnhwl, is fixed to the rim 1, it is obvious that the nut 8 being swivelly connected with the lug; I will move along the projecting end of the bolt and hence move the said lug outwardly. This will cause the strip in move transversely oi? the fixed rim, and hence remove the do mountable rim. Thi swivel connection oi the operating out 8 with the bolt 7 makes the removal or replacing of the demountublv rim carrying strip automatic. and greatly iucilh tates this operation.

This device forms a very simple and n venicnt means for mum-acting deuwuuiubie rims with the fixed rim of the vehicle wh 'ei. The novel arrangement of parts greatly ex pedites the removal or placing of the do mountable rim upon the wheel, and when in position, securely holds the rim to the Wheel and prevents any possibility of accidental dis-- engagement. The extreme simplicity of the construction does not detract from the efficiency and durability of thc device as the parts when assembled form a very strong connection, and one which is suitable for the various purposes for which it is employed. The device may be also used on a tire carrier.

From the foregoing description. taken in connection with the accompanying drawings, if is thought that a clear and comprehensive understanding of the construction, operation, and advantages of my invention may be had. and while I have shown and described the device as embodying a specific structure, I desire that it be understood, that such changes may be made in said structure carrying member confining the demountable rim against lateral movement with relation to the carrying member, an inwardly extending lug on one terminal of the carrying member disposed laterally of the fixed rim, :i bolt carried by the fixed rim extendin tin-oi l the inwardly directed lug, ant

A dcmouniable rim fastener including a body member, lugs carried by the body number spaced apart a distance sufficient to remina demountable rim therebetween and to prevent lateral movement thereof, an angular terminal at one end of the body a!" ranged to overlie a fixed rim, and means to secure the angular terminal to a fixed rim.

A dcmountablo rim fastener including a body member adapted to be confined against rotary movement between fixed and demountable rims, said body member having an extended terminal, means to secure the extended terminal in position upon a fixed riiru and lugs carried by the body member arranged apart a sufiicient distance to acconlmodnte a demountable rim therebetween and secure such rim against lateral movement In testimony whereof I afiix my signature hereto.
